On Modify binder interface, as illustrated in Figure 6.2.38, the user can easily modify the binder by adding control lines to change the binder to a desired shape.

l CONTROL LINES
This function is used to list the added control lines, as shown in Figure 6.2.38. In the list, point the cursor to any control line in the list and double click the left mouse button, the program will automatically display the corresponding serial number for all control lines for the user to identify. Therefore, the user can select the serial number to perform edit and delete operations.
l ADD
This function allows the user to add control lines on binder. Once this button is selected, two methods for adding control lines appear on the interface, as shown in Figure 6.2.39. When using the first method, the user can directly use the cursor to select a point on binder and then drag the mouse cursor to generate a control line. The cursor should be on the binder when selecting point. After the control line is added, EDIT and REMOVE buttons are activated, as shown in Figure 6.2.40. Another method is to select BY INPUT and activate DX, DY and VECTOR. DX indicates the X coordinate for distance with stamping center. DY indicates the Y coordinate for distance with stamping center. The user can input DX value, DY value or DX, DY value to accurately control the location of control line. Then, select VECTOR to define the vector direction of control line. In the end, select CREATE to generate a control line with user defined location, as shown in Figure 6.2.41.

Figure 6.2.41 Add Control Line
NOTE: When adding the control lines, it is suggested to use the top view. The location of control lines had better to be at the boundary of part so that the user can modify binder conveniently. In addition, APPLY can only be activated when there are intersecting control lines.
l EDIT
This function allows the user to modify control lines. Select a control line in the Control Lines list and click on this button to display a 2D window, as shown in Figure 6.2.42. In the 2D window, the control lines and part section lines for their locations are displayed. The user can change the binder by editing control lines so that the binder shape is more suitable for the part. After editing a control line, the user can directly select another control line in 3D window by cursor for editing in the 2D window without exiting the 2D window.

The functions for 2D window are described below:
In the 2D window, the user can add control points on control lines by simultaneously pressing Shift key and clicking the left mouse button, as shown in Figure 6.2.43; move the locations displayed in 2D window for control lines and section lines by simultaneously pressing Ctrl key and clicking the middle mouse button, as shown in Figure 6.2.44; and scale the control lines and section lines by simultaneously pressing Ctrl key and clicking the right mouse button, as shown in Figure 6.2.45 and Figure 6.2.46.

GRID
Display the grid in 2D window. If this option is toggled off, the grid will not be displayed.
WHITE
Set the background color of 2D window. If this option is toggled off, the background color turns from white to black.
REDO
Redo the latest operation. If there is nothing to redo, this button is disabled.
UNDO
Cancel the latest operation. If there is nothing to cancel, this button is disabled.
X, Y, Z
Display the coordinates of the selected control points. The user can enter the Z coordinate value manually and press ENTER to confirm.
dZ
Display the relative distance between the location after moving and the initial location of the selected control point along Z direction upon the global coordinate system.
R
This function is activated when two sides of the selected control points are straight lines. The user can enter the radius value manually and press ENTER to confirm. The program will generate an arc, as shown in Figure 6.2.47.
Figure 6.2.47 Generate Arc
DIST TO PART
Display the distance between control point and part. The user can enter the distance value manually and press ENTER to confirm. The selected control point will move to the entered distance location.
LEN
Display the length of the selected line segment.
STRAIGHT
This option is activated after a line segment is selected. If the selected line segment is curve, the user can select this option to change it to a straight line.
CURVED
This option is activated after a line segment is selected. If the selected line segment is straight, the user can select this option to change it to a curve.
VIEW DIST
Measure the view distance. Select this option to measure the distance between two points in the 2D window by mouse cursor, for example, the distance between control line and part section line at the location for control line, as shown in Figure 6.2.48. The distance value will be shown in the displayed dialog box as illustrated in Figure 6.2.49. The user can also use this function to measure the distance between two points in the 3D window.

Figure 6.2.49 Display View Distance
REF LINE
Display the user selected line as the reference line for control line shape. The user can generate part boundary lines by Create Boundary Line function described in Section 5.1.5 . Then select the part boundary line as the reference line for control line shape, as shown in Figure 6.2.50.
Figure 6.2.50 Display Reference Line
REMOVE POINT
Remove the selected control points.
RESET
Restore the latest setting to the previous one.
The user can change the shape of control lines via moving the control point by cursor, as shown in Figure 6.2.51. When moving the control point, the control lines on screen will highlight the moved control points, as shown in Figure 6.2.52.
Figure 6.2.51 Move Control Point
Figure 6.2.52 Display the Moved Control Points
l REMOVE
This function allows the user to delete the unnecessary control lines.
After completion of editing for all the added control lines, click on APPLY on Modify Binder interface. The binder will change in accordance with the shape of control lines, as shown in Figure 6.2.53.

NOTE: To binders added for symmetric part and symmetric double attach, the Binder Modify supports adding and editing control lines simultaneously.
